Located near the petroglyphs of the Grimes Point National Recreational Trail, Picnic Cave’s tufa formations seem similar to the brain coral of a tropical reef. Unlike coral, the Picnic Cave formations were never alive. But they were once underwater. Ten thousand years ago, at the end of the last ice age, a vast lake covered much of the Great Basin. It’s possible today to see the horizontal lines in the rocks beneath the cave that show the prehistoric shorelines.
